It might not be the most efficient way... Say, let's check out Mavka. @mi mavka.
Def 32, Vit 55.
Size: Medium, Race: Plant, Element: Earth3
For simplicity sake I will assume you are using dagger class weapons and you have access to a gladius[3] +5.
Str 92 (with all bonus and buffs), gladius +5:
Code:
ATK = 92 <STR> + pow(9,2) <STR> + 105 <gladius> + 5*5 <gladius upgrade> = max damage: 303
If you want to make an overall anti-earth weapon using cards, you would insert 3* Kaho cards (each gives +20% damage against earth monsters), therefore your gladius would deal 160% damage.
Code:
max damage * card modifiers: 303 * 1.6 = 485 max damage
Now, if you wanted to make a perfect anti-mavka weapon you would input the following cards:
- Kaho card, +20% attack against Earth.
- Scorpion card, +20% attack against Plant
- Skeleton Worker card, +15% attack against Medium and +5 Attack
Code:
max damage * card modifiers: (303 +5 <skel worker>) * 1.2* 1.2* 1.15 = 308*1.656 = 510 max damage
On the
other hand from the elemental table we can see Earth3 gets 200% damage from Fire element. Let's assume a fire gladius +5 then (can be forged by a player):
Code:
max damage * element modifiers: 303*2 = 606 max damage
Now, please bear in mind the Fire Gladius is much cheaper than either 3 Kaho cards or especially Kaho+Scorpion+Skel Worker cards.
The fun thing: those stack. So, let's assume we are using anti-earth gladius and we have a fire endow:
Code:
max damage * card modifiers * element modifiers: 303 * 1.6 * 2 = 970 max damage
-----
In conclusion: I suggest you to get a set of elemental weapons of your class (fire being the most popular) and not worry about cards yet.
An exception: you might want anti-shadow (X* Santa Poring Cards) weapon, because SPC cards are obtained from Gift Boxes and you can get them fairly cheaply. They have a beautiful synergy with Priest's Aspersio (because we get both an elemental modifier and a card modifier) against Shadow/Dark enemies, but other than that I suggest you to keep the cards until you transcend (and use improved weapons which are trans-only) and stick to elemental weapons for now.
Cheaper and can be more efficient, unless you have access to an endow sage.
It is only my suggestion though :-).
Hope the above helps.
